This working document presents the results of the most significant cephalopods caught on the Porcupine Spanish Groundfish Survey (SP-PORC-Q3) in 2020. Biomass, abundance, geographical distribution and length frequencies were analysed for Eledone cirrhosa (horned octopus), Bathypolypus sponsalis (globose octopus), Todarodes sagittatus (European flying squid), Todaropsis eblanae (lesser flying squid), Loligo forbesi (veined squid), Illex coindetii (broadtail shortfin squid), Rossia macrosoma (stout bobtail squid) and other scarce cephalopods. The biomass and abundance of the most common cephalopods increased, especially I. coindetii and T. sagitattus. In contrast, T. eblanae and B. sponsalis decreased in this last survey. E. cirrhosa and L. forbesi remained at very similar values to the previous year and most of the usually scarce species also generally increased their biomass, with the exception of A. lichtensteinii, R. minor and S. oweniana, which decreased.
